OK - no answer, so let me rephrase: if I use the am33xx_pwm and bone_pwm_P9_21 dtbo's I can see /sys/devices/ocp.3/pwm_test_P9_21.11 period polarity and run files.
If I use the cape-universal instead and config-pin P9_21 as pwm all I get is a confirmation that it occurred, but I have difficulty finding the period, polarity, run files.
